To solve this problem, we will use the formula for permutation. A permutation is where the order of the things in the set matter.
Solution:
₁₂P₅ =

= 12 x 11 x 10 x 9 x 8 = 96,040 different ways that can be made.
u have to multiply if im sure, if this helps
2(n + 5) = -2
First, our goal to this problem is to get the variable (n) and an unknown number on each side. To start off, we can divide both sides by 2.

Second, we can go ahead and cancel 2 out, which will replace it with a -1.

Third, our next step will to be to subtract 5 from each side.

Fourth, our last step is to simplify -1 - 5. This is quite simple. -1 - 5 = -6, so -6 is what the variable (n) equals.

Answer:
Answer:
Step-by-step explanation:
When two variables are directly proportional, then an increase in the value of one variable would cause a corresponding increase in the value of the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the value of the other variable.
The volume of a gas is directly related to the temperature of the gas. If V represents volume, T represents temperature and k represents the constant of proportionality, the expression becomes
V = kT
At 20 degrees Celsius a certain gas has a volume of 125 cubic centimeters. It means that
125 = 20k
k = 125/20
k = 6.25
The equation becomes
V = 6.25T
When T = 50 degrees Celsius, the new volume would be
V = 6.25 × 50
V = 312.5 cubic centimeters
